Has anyone here worked extensively with resin bond diamond tools? I’m considering them for applications where surface finish and minimal chipping matter more than aggressive stock removal - especially on brittle materials like ceramics and glass.
For those who’ve used them:
Did you see a smoother finish compared to the metal bond?
Any trade-offs in tool life or speed?
What feed/coolant setups worked best?
Would appreciate your insights.
Use caution. Be careful. Safety gear should be utilized.
Diamond bits can grab ceramic rather forcibly and might cause harm from fragments to eye, or any exposed flesh. Cover self and face with full screen shield clear with headlight on top to give self best view. I have a 12th century vase which if correct came from Korea but has handles similar to period used only in Aztec culture same time frame as 12th Century. Painted vase seems covered in cement as ceramic could be from period. Tested as Emerald. Weird should test as ceramic.
Emerald is not native to Korea in 12th century.
Painted in style of 12th year crane with artist signatures across vase.
More research topic more weird this thing gets.
About to break it apart just to see if it holds secrets within. Except so hard Diamond bits do not drill into it. Doubt throwing on ground would break vase. Typical ceramic of period was never that sturdy. Most broke due conflict after conflict. Few in museum. They match same painting style on vase front & back.
Paint developed gas pockets upon getting to my region the paint literally broke in 4 locations and evaporated. Exposed ceramic appears to be cement mixture with lot of cement on base as if item was attached to a pillar or staff. Vase could be used as a weapon it is stronger than most I have ever seen. Abnormal for ceramic to be heavy. Paid $25 for vase from 12th century. I Think vase is newer and was cemented into shape to conceal something else inside. Not been able to remove base of vase or even get past cement yet.
From what I’ve seen, resin bond diamond tools are a good choice when surface integrity matters more than tool life. They cut ceramics and glass with noticeably lower chipping because the bond releases abrasive more cleanly. The trade-off is faster wear, so good coolant flow is important to keep the wheel from loading. If the goal is a smoother finish with fewer post-polishing steps, resin is usually the better option.
Resin-bond diamond tools are great when you need clean edges and minimal chipping on ceramic or glass. They wear faster, so make sure you use plenty of coolant, but they deliver a smoother finish with less polishing afterward.
Agreed - for brittle materials, resin bond usually gives the cleanest edges with minimal chipping. They wear faster, but with steady coolant the surface finish is far better and reduces polishing time.
I agree with everyone here speaking of bonded tool’s and the finish they produce. An example is a 600 grit metal lap will give a 600 grit finish. A 600grit resin bonded lap with give a finish of 1200 grit basically. Sometimes better depending on manufacturer and use skills. Yes they definitely wear faster but are ideal for certain materials.
Interesting vase you have acquired. It’s a shame I don’t live closer. I would love to see and feel it. If you ever figure out what it is really made from I would be very interested in your findings.
Based on tests conducted using MOHS hardness comes in as Emerald.
Ceramic vase should come in at glass.
Considering cutting in half with facet Diamond blade or buying a laser to cut exterior cement off vase. No clue what I have. Will be fun tearing apart. Might use as target practice if I get angry enough.
It’s interesting that it’s so tuff yet not hard. I know hard can be brittle. Lol. Target practice is a great idea when you are tired of thinking about it. I have used several things over my 6 decades for target practice that people looked at me funny for using them. Lol lol.
